摘要：
The electric-field-gradient tensor fluctuations at the As75 site in ferroelectric RbH2AsO4, RbD2AsO4, and KH2AsO4 have been studied as a function of temperature and applied electric field. The measurements allow a direct determination of the Slater short-range energy parameter ε and provide a test of the nature of the ferroelectric-mode-type elementary excitations. © 1969 The American Physical Society.
